IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specilication forming part of Letters Patent No. llS, dated March 28,1876; application filed November 6, 1873.

To all lwhom it may concern Be it known that I, EBEN T. STARR, of thecity, county, and State of New York, have invented a new and usefulImprovement in Revolving Fire-Arms; and I do hereby declare that thefollowing is afull, clear, and exact description of the same, referencebeing had to the accompanying drawing, forming part of this'specification, and in which- Figure l represents a side view of arevolving fire-arm having my invention applied to it. Fig. 2 is asimilar view of the same with the revolving cylinder partly broken away,and with the shellextractor in a changed position. Fig. 3 is a sectionallongitudinal view ofthe rear and operating portion of the arm 5 and Fig.4, a transverse section, in part, at the line x in Fig. 3.

My invention relates to that class of revolving lire-arms in which thecartridge isinserted from the rear ot the cylinder.

The invention consists in a novel and advantageous construction oftheshell-extractor, which is composed of a sliding rod or bar and swingingyoke. It also includes a novel arrangement of a movable nose on thehammer, to adapt it to both center-hre and rim-fire cartridges.

In the accompanying drawing, A represents the stock, B the revolvingmany-chambered cylinder, C the hammer, and D the barrel, of the arm. A y

The cylinder B is rotated, to bring its chambers b successively in linewith the barrel, by the usual or any suitable means in the act ofcocking the hammer. These chambers b I form with shoulders b', or of areduced diameter at their forward ends, to adapt them to langelesscartridges, said shoulders acting as astop or bearing for the forwardend of the shell of the cartridge to rest against to resist the blow ofthe hammer when the cartridge is being exploded, and serving to retainthe shell after explosion, but allowing of the free passa-ge ofthe ballout of the chamber.

By using iangeless cartridges, as shown in Fig. 3, it is practicable toarrange a greater number of chambers ina cylinder of given d1- ameter.Cartridges with flanged heads, however, may be used in the same cylinderwhen desired, as, for instance, by charging only every alternatechamber.

The shell-extractor E consists of a rod or bar, c, iitted to slide on orthrough a swinging yoke, d, pivoted, as at e, to the' stock or frame, onthe off -side of the latter relatively to the direction in which thecylinder B revolves and in front of said cylinder, so that, when theyoke d is swung downward and the bar cslid backward through the yoke,said bar lies in proximity to or against the side of the frame, and isout of the Way, as represented in Fig. l ot' the drawing.

When it is required to remove the shell of an exploded cartridge, theyoke d is reversed or swung upward by suitably pressing' on the bar c,and the latter then slid or projected through the yoke and chambercontaining the exploded shell, see Fig. 2,) so as to drive or force outthe shell in the rear. This done, the bar c is slid in the reversedirection again through the yoke, so as to clear the cylinder, and theyoke swung to its normal position, with the sliding bar set backwardagainst the side of the frame, as in Fig. l.

A guard, j', may be attached to the back or opposite end of the bar c tothat which presses on the shell to remove it, so that when the extractoris adjusted to its quiescent position, as in Fig. l, said guard lies inclose proximity to the rear end of the'eylinder B, and acts as a stop tokeep a newly-inserted or unexploded cartridge in the chamber, which itforces from dropping out in rear of the cylinder. This guard f may beformed by simply bending or shaping the back end ofthe bar c, as shownin the drawing.

The extractor .E is held in its closed position against the sides of theframe by a spring, in conjunction with a catch, g, and stop h, orotherwise.

To adapt kthe hammer C to both center-iire and rim-fire cartridges itisfitted with a movable nose, 7c, which may be so changed or set inrelation to the face of the hammer as, for instance, by constructing therear end of the nose with a screw-thread, and screwing said nose intoone or other of the two screw-holes ZZ in the hammer, that the -point ofthe nose 2. The detachable nose k, in combination is made to strikeeither the center or rim of 4 with the haxnmerU, formed with the twoholes the cnrtridge,as required. l l', whereby the nose k may be appliedto What is here claimed, and desired to be seeither one of said holes,so as to serve as acured by Letters Patent, istiring-pin for eithercenter-irng or rim-firing l. The shell-extractor E, composed of aslidcartridges, as'shown and described.
